Media 7 October 2015 David Cameron made a terrible sex joke in his Conservative party conference speech And he looked really pleased with himself afterwards. All pictures: BBC screengrabs. Sign UpGet the New Statesman's Morning Call email. Sign-up As if the general public wanted to know anything else about the Prime Minister's sex life, he's gone and forced some more unsavoury images into our minds. 64 of them, to be precise. During a particularly grim section of his speech to Conservative party conference, David Cameron took a break from his vague security theme (essentially: "Drones, lads! Who's with me?!") to tell a miserable sex joke. He began by talking about Labour's "economics guru", Richard Murphy – classic foreplay – before deploying this awkward punchline: "His book is actually called The Joy of Tax. I’ve got it. I took it home to show Samantha. It’s got 64 positions – and none of them work." Here he is, building up to his sex joke. Relaxed, in control: Here he is, telling the joke. Part anxious, part relieved: Here he is, when laughter ensues. Gleeful little schoolboy: And here's Samantha. Eyes betraying bitter hatred: › David Cameron’s promise to create “Generation Buy” is yet another housing policy that’ll make things worse I'm a mole, innit.
